GRAIN-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 485,520, dated November1, 1892. Application filed October; 10, 1891- Serial No. 408,305- (Nomodel.)

To all whom it may concern.-

- Be it known that I, JOHN A. L. WILSON, a citizen of the United States,residing at Woodland, in the county of Iroquois and State of Illinois,have invented a new and useful Grain-Elevator, of which the following isa specification.

My invention relates tohoisting apparatus; and it has for its object toprovide a device of this character which is designed to be usedparticularly for the handling of grain now ordinarily done by the scoopshovel, having principally forits object to expedite the elevation ofthe grain into the cribs and granaries and to provide means whereby ahigher elevation can be reached than with the ordinary scoop-shovel,thus rendering it possible to store greater quantities of grain underone roof and also facilitating the removal of the grain from thegranaries back into the wagon without scooping it out, and lastly by itsuse obviating the necessity of building cribs too near the ground, wherethe same is liable to injury from rats, mice, and dampness.

With these and other objects in View, which will be readily apparent asthe nature of the invention is better understood, the invention consistsin a grain or hoisting derrick having means for elevating the wagon-boxand tilting the same and also means for receiving and conducting theelevated grain into the cribs or-bins, all of which will be hereinaftermore fully described, illustratedin the accompanying drawings, andspecifically pointed out in the appended claims.

In the accompanying drawings, Figure l is a perspective view of agrain-hoisting apparatus constructed in accordance with my invention,the wagon-box being elevated therein and in a position for dischargingits contents. Fig. 2 is a detail in perspective of the grain-chute. Fig.3 is a similar view of the detachable wagon-box clamp.

Referring to the accompanying drawings, 1 1 represent parallel sills orrunners, upon which the derrick or hoisting-frame is mounted, and arespaced apart a suitable distance to permit the passage of an ordinarygrainwagon the'rebetween, and when designed to remove the apparatus fromone crib to another the said sills or runners are connected inner orrear half 8 in order that the hoistat one end by the reach or crossbar2, which not only prevents the derrick from spreading,

but provides means whereby a team may be readily hitched to the same forthe removal. gExten'ding vertically from near each end of the runners lare the uprights or standards 3, connected in pairs at their upper endsby the braces 4, parallel, with the runners and each other, and areadapted to hold the two uprights extending up from each runner suitablyspaced apart, while all of the posts or uprights are braced together bythe horizontal side and end braces 5, which are of any suitable number,according to the strength with which it is desired to construct theframe, which is made of a height sufficientto reach the highest cribs orbins. Supported upon one of the sills or runners '1 and between thelowermost brace 5 from that side of the frame are the opposite parallelbars or posts 6, in which is journaled the horizontal winding-drum orshaft 7, having the forward half 8 of greater diameter than the 7 bing-ropes 9 and 9 ,respectively, will be wound at different velocities,so that the front. rope 9 will hoist or elevate more rapidly than. therear hoisting-rope 9. The shaft or winding-drum 7 carries upon one endoutside of one of the bars 6 a large spur-wheel 10, meshing with thesmaller pinion 11 directly therebeneath and carried bythe horizontalshaft 12, journaled in said bars or posts beneath the winding-drum 7.Crank-handles 13 are carried upon each end of said shaft 12 and areadapted to revolve the pinion 11 in order to revolve or rotate thewinding-drum, said shaft 12 being kept from turning backward by means ofa ratchet-wheel 14, secured 0 upon one end thereof outside of one of thejournal-posts 6 and engaged by the pawl or dog 15.

Each of the hoisting-ropes 9 and 9 extend up one side of the frame orderrick and pass over the guide-pulleys 16, secured centrally to one ofthe connecting-bars 4 at the top of'said frame and from saidguide-pulleys are passed over the supporting-pulleys 17, secured uponthe cross-bars 18, restingacross the parallel I00 bars 4 near each endthereof, so that the hoistin g-ropes extend from the center of saidcross beams or bars 18 down within the frame near each end thereofand-are provided'at their ends with the engaging-hooks 19, that areadapted to engage the clamp encircling the front and rear ends of thegrain-wagon box 20, that is carried within the frame or derrick betweenthe runners and the opposite parallel uprights and directly beneath saidhoisting-ropes. Upon one end of the wagon-box 20 is secured thestationary clamp or yoke 21, which comprises the parallel plates orblocks 22 and 23, taking under and over the boxbody, respectively, andbolted together at the sides thereof by the connecting bolt-rods 24,while the upper or top plate or block 23 is provided with an eye 25,secured thereto, that is adapted to be engaged by one of the hooks 19 atthe lower ends of the hoisting-ropes,- said clamp, as said, beingdesigned to be stationary upon the front end of thegrain wagon box,where it will be out of the way of' loading and unloading the same. Uponthe rear 'GIldaOf the box-body is designed to be attached a de tachableor removable'clamp 26, which is=1designed tobe connected to the'box-bodyafter the wagon has been driven-within the-frame and. detached from thesame after the grain has been removed and. discharged. Theremovableclamp 26 is providedwith atop block or cross-bar 27, that is adapted torest upon the top of the box-body, andthaswsecured by means of bolts onother securing meansto the top thereof the eye 28, from-which saidblockis supportedby thehook -19 atthelower end of the rearhoisting-r0pe9. Loosely secured in perforations in each end of'saidcross-bar 27 are the side-securing rods-r29, provided with lowerarrow-head or shouldered portions or ends 30, while their upper ends,extending above-said cross-bars,=are squared to receive theoperatingf'levers- 31,

suitably keyed thereon. and adapted to'res volve saidrod. Abottom-supporting bar 321 is adapted to be placed beneath therwagom bedand is secured thereto by means. ofthe upper portion of the detachableclamp 26 be ing connectedlthereto, said bar 32 .beingrpros vided withlongitudinal slots 33, through which the arrow-heads 30 ofthe'securing-irods' 29 pass andengage beneath said barron either side ofthe i slots therein by being turned af-. ter insertion by means. of theturning levers 31, secured upon the upper endsof said rods.

Upon the rear uprights 3. are secured the seriesof rearwardly-extendingchute-rests 34; secured inzpairs along said rearcend onwthe frame,according to the various heights to which it is designed to elevate thewagon-bed; but said rests are not secured tothe'frame parallel with eachothexybut are alternately disposed, or at least arranged in :difierentob-: lique planes, so that the grainfchute 35,which is secured thereonupon the outsidetand at therear end of the frame, will have a sufficient incline to conduct the grain into the cribs or bins which aredesired to be filled. Said rests 34 are suitablybraced by the braces34:, and, as said, are designed to accommodate the elongated chute -85,which is securely bolted to the same. Said chute 85 is placed upon thepair of rests, which are at the height of the bin or crib to be filled,and are provided with inclosing side walls 36 and the rear end wall37,while the top and one end of the same are open for the receiving anddischarging of the grain; A folding leaf 38 is hinged to one side at 39to the top edge of one of the inclosing sides 36 of said chute and whenopen is designed to take beneath the rear end of the elevated wagon bedwithin the derrick and conduct the grain within said chute. The foldingleaf 38 is provided with an enlarged end 40, that compensates *fortheslant of the chute and from which turns up the upwardly-extending endflange 41, projecting up one side of the wagon-bed and preventing thegrain from :wastingover the edge of said leaf, the same being supportedbeneath the end of the wagon-bed by the braced rests orseats 42,

secured to the outside ofthe side 36, to which the leaf is hinged, whilethe same is supported withinithe chute-when notin use uponvsimilar,rests or seats 43, secured; upon the inner face'of'. said side. 1

It is-thought that the operation of: the device is now-apparent. The bedof the wagon, which has been previously drawn within the frame orderrick, is hoisted-by means-of the hoisting devices described, andowingrto the different diameters of the rhoisting-drurn Y or shaft the'frontend of said bediselevated by the hoistiugerope 9 5 more rapidlythan the rear endof-the same is-hoisted by the rope 9 Thus as the bed iselevated up to the desired height the i same is also-tilted, so.thatwhen the end gate is open: thegrainiwill readily pass-overthe leaf38' of the grain-chute i into said chute and from thence 'into :the bin.or crib in the "mannertobe 'readily seen,

Relative to the :use of": the stationary and detachable cl-amps hereindescribed it may be stated that in actual. practice/the stationary clamp-or yoke is-designed to be'secured :on both endsof the wagon box andremain there, while the detachable clamp is particularly de-. signed forthe useof grain-ibuyersand are in such cases also applied .to 'bothendsof the wagon-box in the t same mannert-asthe stationary clamps;butt-heir use is optional, and the same 1 may be Lemployedinterchangeably withzeach other.

In order that access: may be readily had to at one end of the frame,substantially as set forth.

2. The combination of a clamp detachably connected to the wagon body orbed, thesame comprising an upper cross bar or head having an eye adaptedto be engaged'by said hoistingropes and perforations at each end,clamping rods journaled in said perforations and provided with lowerarrow-head or shouldered ends and upper squared portions,operatinglevers keyed upon said squared ends, and a lower parallelsupporting-bar adapted to rest beneath the bottom of the bed or body andprovided at each end with slots adapted to be engaged by the shoulderedends of said clamp- 25 ing-rods, substantially as set forth.

3. In agrain-elevator, the combination, with the frame and hoistingdevices within said frame, of an elongated grain-chute removablysupported upon one end of said frame and provided with an inclosing endand sides, a table or leaf hinged to the upper edge of one side of saidchute and provided with an enlarged flanged end, said leaf beingdesigned to take beneath the tilted end of the elevatedgrain-receptacle, and braced rests secured upon the outer and innerfaces of one side of said chute and adapted to support said leaf ortable in its open or closed position, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
